Skin microbiome maintain homeostasis with the host, and affect skin barrier and immune function. The components of skin microbiome are diverse and specific, and are affected by multiple factors. The predominance of Staphylococcus aureus and decrease in diversity of skin microbiome are a characteristic of atopic dermatitis. The overgrowth of S. aureus can aggravate inflammatory reactions in AD. S. epidermidis, although another predominant bacterium in AD, exerts an immunoprotective role by regulating skin barrier?associated immunoreactions through the dendritic cells, interleukin (IL)?17A?producing Th17 cells/IL?17 pathway, and by suppressing the overgrowth of S. aureus. Malassezia can induce and aggravate inflammatory reactions in AD through colonization, sensitization, cross reactions, and other mechanisms. Studies on skin probiotics may provide new directions for the treatment of AD.

Objective To evaluate the recognition and uptake of transglutaminase 3 (TG3) by dendritic cell-specific intercellular adhesion molecule 3-grabbing nonintegrin (DC-SIGN) receptors on the membrane surface of DC-SIGN-transfected human embryonic kidney (HEK) 293T cells and monocytederived dendritic cells (MDDCs).Methods The eukaryotic expression vector pGCMV-enhanced green fluorescent protein (EGFP) containing DC-SIGN gene fragments was transfected into HEK293T cells to prepare DC-SIGN-EGFP-HEK293T cells by using liposome transfection method.CD14+ monocytes were isolated from peripheral blood samples by magnetic bead-based negative selection,and then were induced by granulocyte-macrophage colony stimulating factor (GM-CSF) and interleukin-4 (IL-4) to prepare MDDCs.Laser confocal microscopy and flow cytometry were performed to evaluate the recognition and uptake of TG3 protein by DC-SIGN receptors on the surface of HEK293T cells and MDDCs.MDDCs treated without Alexa Fluor 647 dye-tagged TG3 served as blank control group,and those treated with Alexa Fluor 647 dye alone served as negative control group.Results After co-culture with TG3 for 3 hours,laser confocal microscopy and flow cytometry both showed that TG3 could be recognized by and uptaken through DC-SIGN receptors into HEK293T cells and MDDCs.Flow cytometry also revealed that the binding of TG3 to MDDCs could be partially blocked by DC-SIGN blocking antibodies.Neither the negative control group nor the blank control group showed the recognition and binding of TG3 to HEK293T cells and MDDCs.Conclusion TG3 can serve as a kind of autoantigen to be recognized and bound by DC-SIGN receptors,followed by uptake by dendritic cells.

A rapid, sensitive, label-free and separation-free analytical method for determination of melamine ( MA) was developed based on surface enhanced Raman scattering ( SERS ) effect of gold nanoparticles. Through tri-sodium citrate reduction method, gold nanoparticles with average diameter of 30 nm were obtained. The melamine detection platform was constructed after self-assembling 4-mercapto phenylboronic acid (4-MPBA) on the surface of gold nanoparticles through Au S covalent bond. When MA existed in solution, 4-MPBA functionalized gold nanoparticles would aggregate because of strong hydrogen bond interaction between MA and 4-MPBA. Moreover, following increase of the concentration of MA, gold nanoparticles would aggregate more intensively and form more hot spots. As a result, Raman signal of 4-MPBA and MA was enhanced greatly. The characteristic Raman peaks of 4-MPBA and MA respectively located at 1076 cm-1 and 715 cm-1 . Hence, the qualitative and quantitative detection for MA were realized based on the ratio value of I715 cm-1 to I1076 cm-1 . The linear range of MA detection was 0 . 1 μmol/L-1. 5 μmol/L. The limit of detection (LOD) reached 0. 02 μmol/L in terms of three times signal to noise.
